In process control theory, image processing is the core of industrial sugar crystallization. It lays a solid foundation for the later part of the modeling and optimization of image processing system. Using a visual sensing method, this design is based on S3C2440 embedded processor hardware platform and Windows CE 5.0 operating system image information acquisition system of sucrose. This paper introduces the design of image sensor interface and the Implementation Stream Interface Driver in detail. This design has a friendly man-machine interface, and has functions like real-time monitoring, camera, storage and others. The design reduces system complexity, saves space and reduces costs.
